Within the Homosexual community:
When the recipient of Gloryhole sexual activity (usually anal sex), stays in the cubicle for more than one session.
Also, when performing oral sex on multiple partners in a gloryhole, it can be described as "queing for food".
-"Dude, I heard that Nathan totally qued in the toilets at Thorpe Park for like an hour!"
-"I heard he qued for food, the sicko!".
